  • Abstract
    In this paper, we propose an Auto-tuning (AT) function with an AT language for a dedicated numerical library with respect to supercomputers in operation. The AT function is based on well-known loop transformation techniques, such as loop split, fusion, and re-ordering of statements. However, loop split with copies or increase of computations, and loop fusion to the split loop are taken into account by utilizing user knowledge.
